High Phosphate 2500 - Options?

[cheshamjim]

Thanks for your reply, Waterbear.

I am understanding from your comments that it isn't necessary to worry about the high phosphate content, so I won't (no more Sea Klear for me).

Regarding the chlorimine problem I have, I am adding about 6 lb of granulated dichloro shock on a daily basis (I'm trying to use up what I've already paid for at the pool store) in order to keep my FC at a high level. I have no way of knowing how far above 5 ppm it might be, since my test kits (DPD #1 and OTO) only read to 5 ppm. I'm wondering if I could dilute my water sample with a measured amount of tap water to get a reading that shows on the color comparator, them multiply by the dilution amount. For instance, if I add one tablespoon of pool water to two cups of of tap water, I would have a dilution of 1:32. If the diluted sample read 1 ppm, them actual FC content could be derived by multiplying 2 ppm X 33. Do you think this would work? I need to find someway to quantify high FC content until my RS234 kit arrives.

I want to achieve "breakpoint" chlorination and I understand this requires raising and maintaining (for one week) FC levels that are 5 to 10 times the chloramine levels. In my most recent test at the pool dealer, my CC was 3.2. I guess that means I need to maintain FC for one week at 16 to 32 ppm. Am I thinking correctly?

I've drifted pretty far from from the phosphate issue, but that's what started all this. If I'm incorrectly posting, I'm sure one of the Super Moderators will let me know.

Anyway, this forum and PoolSolutions.com have moved me from very deep dispair only one week ago to where I feel pretty darned confident that I can get things right at last without spending yet another huge lump of $$$.

My best regards to all who help folks like me. I have learned so much in such a short period of time.
